Random Request timed out when ping router?

regarding VLANS & tagging
VLANs, trunks and tagging are all related. As you probably know a VLAN defines a broadcast domain, trunks allows vlans to travel from switch to switch and taggings either use the InterSwitch Link (ISL) which is Cisco proprietary or the open standard 802.1q. So to put it a bit more simply a trunk permits different [...]

Is it loop in Network
This WILL create a potential spanning-tree loop – which may and may not create problems, depending on the capabilities and configuration of the switches involved. If they all are configured to handle spanning-tree properly (default for a Cisco workgroup switch often is), then the switches will realize this, and effectively block traffic on one of [...]
